Brisbane completed a sweep of its eight-game regular-season series with Sydney, taking game four of the away leg 13-5 on Sunday.

The Bandits became the first team in ABL history to win all its regular-season games against an opponent on the back of a five-run fourth in scorching conditions at Blacktown International Sports Park.

Brisbane turned a 4-1 deficit into a two-run lead as they chased the previously solid Clayton Freimuth from the game.

T.J Bennett homered for the ninth time this season after Freimuth walked Donald Lutz and the Bandits added runs on a David Sutherland groundball and sacrifice fly by Adam Weisenburger.

Andrew Campbell capped off the inning with a solo home run - his first of two in the contest - to make it 6-4.
